Warm-season grass
Bahiagrass Lawn Care Schedule
Bahiagrass is a warm-season grass grown across the Gulf Coast and Florida for its toughness on poor, sandy, acidic soils and its deep roots, which make it very drought- and heat-tolerant with minimal irrigation. It forms an open, coarse-textured turf and throws up tall Y-shaped seedheads that mean frequent mowing in summer — the trade-off for how little else it asks.

Key care windows
Timing windows are flexible (early / mid / late) and tuned to a typical transition-zone season — soil temperature and your local weather should always have the final say.
Spring pre-emergent (crabgrass)
Apply a pre-emergent herbicide as soil temperatures climb through the low 50s°F — before they reach the ~55°F at which crabgrass germinates — to stop summer weeds before they start. A second application 6–8 weeks later extends control through the season.
Don't apply a pre-emergent if you plan to seed — it blocks grass seed too. Always read and follow the product label — it is the legal authority on rates, timing, and safety. These windows are regional estimates, not a prescription; defer to the label and your local extension office.
Spring green-up & first mow
Warm-season turf begins breaking dormancy as soil temperatures reach about 55°F, but it isn't actively growing until the soil warms to roughly 65°F. Once it's about half green, mow low to clear dormant material and let sunlight reach the crowns. Don't fertilize until it's at least 80% green and growing.
First feeding
Make the first fertilizer application 2–4 weeks after full green-up, once the lawn is actively growing. Feed lightly — about 1–3 lbs of nitrogen per 1,000 sq ft per year. On the high-pH or alkaline soils bahiagrass sometimes grows in, yellowing is usually iron chlorosis rather than a nitrogen shortage, so reach for an iron supplement instead of piling on more nitrogen.
Some herbicides used on other Southern lawns are meant to KILL bahiagrass — read the label carefully and confirm it is safe for bahiagrass first. Keep nitrogen at or below ~1 lb per 1,000 sq ft per feeding, and use iron, not extra nitrogen, for high-pH yellowing. Always read and follow the product label — it is the legal authority on rates, timing, and safety. These windows are regional estimates, not a prescription; defer to the label and your local extension office.
Aeration & dethatching
Core-aerate (and dethatch if the thatch layer is over about ½") during the peak growing season, when warm-season turf recovers fastest. Avoid aerating dormant or drought-stressed turf.
Summer feeding program
Summer is the warm-season growth peak. Feed lightly — about 1–3 lbs of nitrogen per 1,000 sq ft per year. On the high-pH or alkaline soils bahiagrass sometimes grows in, yellowing is usually iron chlorosis rather than a nitrogen shortage, so reach for an iron supplement instead of piling on more nitrogen. Spread the annual budget across the season rather than applying it all at once.
Never exceed ~1 lb of nitrogen per 1,000 sq ft in a single feeding. Always read and follow the product label — it is the legal authority on rates, timing, and safety. These windows are regional estimates, not a prescription; defer to the label and your local extension office.
Summer weed & pest watch
Spot-treat broadleaf weeds during active growth, never on drought-stressed turf. Watch for insect and disease pressure in hot, humid weather and treat problem areas rather than the whole lawn.
Final feeding & soil test
Give a final feeding in early fall, then stop nitrogen — late-season nitrogen pushes tender growth into frost. Fall is also the best time to take a soil test so amendments are ready before spring.
Stop nitrogen about 6 weeks before your first expected frost. Always read and follow the product label — it is the legal authority on rates, timing, and safety. These windows are regional estimates, not a prescription; defer to the label and your local extension office.
Fall pre-emergent (winter weeds)
A fall pre-emergent applied before soil cools below about 70°F controls winter annual weeds like Poa annua and henbit.
Always read and follow the product label — it is the legal authority on rates, timing, and safety. These windows are regional estimates, not a prescription; defer to the label and your local extension office.
Winter dormancy
Expect a brown, dormant lawn from first frost until spring green-up. Hold off on fertilizer and pre-emergent. A light watering during extended winter drought helps prevent desiccation.

Bahiagrass care guide
Mowing
Mow bahiagrass at 3–4" with a sharp blade — its tough seed stalks dull mowers fast, and it sends up seedheads so quickly that you will mow often in summer just to keep them down. A dull blade shreds the coarse blades and leaves a ragged, whitish finish.
Watering
Bahiagrass is very drought-tolerant thanks to its deep roots and will go semi-dormant and brown in drought rather than dying, greening back up with rain. Water only about 1" per week when you want it green; it needs far less than most Southern lawns to survive.
Fertilizing
Feed lightly — about 1–3 lbs of nitrogen per 1,000 sq ft per year. On the high-pH or alkaline soils bahiagrass sometimes grows in, yellowing is usually iron chlorosis rather than a nitrogen shortage, so reach for an iron supplement instead of piling on more nitrogen.
Weed control
Bahiagrass's open growth lets weeds in, so a spring pre-emergent helps. Note that atrazine and some other products used on Southern lawns can injure bahiagrass or are used specifically to suppress it — always confirm the label lists bahiagrass before spraying.
Strengths
- Deep roots give strong drought and heat tolerance with little irrigation
- Thrives on poor, sandy, acidic soils where other grasses fail
- Low fertilizer needs and few serious pests
Watch out for
- Open, coarse texture — not a dense, carpet-like lawn
- Constant tall seedheads mean frequent summer mowing
- Not cold-hardy; prone to iron chlorosis (yellowing) on high-pH soils

A starting point — your plan adjusts to your yard
This Bahiagrass schedule is a research-based template for your grass type. Your lawn is one of a kind, though: the right timing and amounts also depend on your soil test, sun and shade, irrigation, lawn size, and the goals you set — a low-input yard, the deepest possible color, or just crowding out weeds. YardLedger takes this template and adjusts it to your yard's specific needs, then keeps refining it from the history of what you've actually done and how the lawn responded — so every recommendation gets more personal over time.
Safety first
Some herbicides used on other Southern lawns are meant to KILL bahiagrass — read the label carefully and confirm it is safe for bahiagrass first. Keep nitrogen at or below ~1 lb per 1,000 sq ft per feeding, and use iron, not extra nitrogen, for high-pH yellowing.
Always read and follow the product label — it is the legal authority on rates, timing, and safety. These windows are regional estimates, not a prescription; defer to the label and your local extension office.
